Modern CMake usage: reworked to use target-specific properties. As with Corrade, this is not exactly backwards compatible, but for common use case without OBJECT libraries this should not be a problem. In any case, recreate the build dir and update your copy of all Find*.cmake modules to avoid weird things happening. User-facing changes: * Documentation of all Find*.cmake modules converted to reStructuredText to follow official CMake guidelines. * The newfangled way to use the libraries is to link to Magnum::Shaders instead of adding ${MAGNUM_SHADERS_INCLUDE_DIRS} to include path and linking to ${MAGNUM_SHADERS_LIBRARIES}. * The old ${MAGNUM_*_LIBRARIES} are deprecated and now just expand to Magnum::* target. Use the target directly. These are also enabled only when building with MAGNUM_BUILD_DEPRECATED. * The old ${MAGNUM_*_INCLUDE_DIRS} are removed as the Magnum::* targets cover these too. Internal changes: * Global state such as include_directories() was replaced with target-specific settings.

# Find OpenGL ES 3
# ----------------
Added FindOpenGLES3.cmake module. Seems that Mesa has both ES2 and ES3 in the same libGLESv2.so. Weird.

Initial support for WebGL 2. The actual WebGL 2 distinction was done as a part of previous WebGL cleanup. It compiles, but is completely broken, as Emscripten has some missing bits to go through at least Context class creation.

${OPENGLES3_LIBRARY_NEEDED}
modules: fixed Find*GL*.cmake, updated coding style. It's meaningless to have *_INCLUDE_DIR point to the dir where {egl.h,gl2.h,gl3.h} exists, because we're always including the files using full path (e.g. <EGL/egl.h>). It then fails miserably at compile time on platforms which don't have the parent directory in include path.
